CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation application of U.S. application Ser. No. 16/179,302 filed Nov. 2, 2018, which claims priority to U.S. Provisional Application Ser. No. 62/583,830 filed Nov. 9, 2017, the disclosures of which are incorporated in their entireties herein by this reference.

BACKGROUND

One billion people lack access to health care systems. Of the 56.4 million deaths worldwide in 2015, more than half (54%) were due to the top 10 causes. Ischaemic heart disease and stroke are the world's biggest killers, accounting for a combined 15 million deaths in 2015. These diseases have remained the leading causes of death globally in the last 15 years. Chronic obstructive pulmonary disease claimed 3.2 million lives in 2015, while lung cancer (along with trachea and bronchus cancers) caused 1.7 million deaths.

Chronic vascular diseases (CVDs) are the number 1 cause of death globally: more people die annually from CVDs than from any other cause. An estimated 17.7 million people died from CVDs in 2015, representing 31% of all global deaths. Of these deaths, an estimated 7.4 million were due to coronary heart disease and 6.7 million were due to stroke.

Most cardiovascular diseases can be prevented by addressing behavioral risk factors such as tobacco use, unhealthy diet and obesity, physical inactivity and harmful use of alcohol using population-wide strategies.

Cancer is the second leading cause of death globally, and was responsible for 8.8 million deaths in 2015. Globally, nearly 1 in 6 deaths is due to cancer. Approximately 70% of deaths from cancer occur in low- and middle-income countries. Around one third of deaths from cancer are due to the 5 leading behavioral and dietary risks: high body mass index, low fruit and vegetable intake, lack of physical activity, tobacco use, and alcohol use.

Further, according to The Veterinary Cancer Society, cancer is the leading cause of death in 47% of dogs, especially dogs over age ten, and 32% of cats. As of January 2015, 39% of dog owners have a dog aged 7 and older, while 43% of cat owners have a cat in the oldest age bracket. These companion animals are under high risk area for cancer.

Additionally, over 7.5 million children under the age of 5 die from malnutrition and mostly preventable diseases, each year.

As such, the use of novel nutrient blends that can address a variety of health conditions in animals, especially those which can improve the quality of life and life span of the animal, continue to be sought.

Example

By way of example and not limitation, the following non-limiting study is illustrative of compositions and methods using nutrient blends in animals, in one or more embodiments provided by the present disclosure.

Example 1—Nutrient Blend Study

Female nude mice with 3-4 weeks age (n=50) were randomized into 10 groups based on the baseline body weight (n=4 to 5/group) which were assigned to one of the ten diets randomly till end of study with one-week transition from original diet to experimental diets. All the diets were freely accessed to the mice. Every week fresh diet was weighted and provided three times to mice. Six weeks after feeding experimental diets, 1×10⁶ human breast cancer cell line MDA-MB231 was subcutaneously injected into right flank of each mouse. Tumor occurrence and size was recorded and measured by caliper every two weeks.

The following diets were used in the study. Control: AIN-93G (available from Research diets, Inc.) (18% protein, 7.2% fat, 63% carbohydrate, 5% fiber, remaining % moisture). AIN-93G+nutrient blend (NB) (replacing 16.46% carbohydrate with 11.3% whole walnut meal, 0.005% maitake mushroom extract, 0.05% EGCG, 3% turmeric root powder, 0.005% lycopene, 0.1% taurine, and 2% fish oil) having 19.9% protein, 9.7% fat, 53.2% carbohydrate, 6.1% fiber, and 11.1% moisture. AIN-93G+turmeric root powder (replacing 3% carbohydrate with 3% turmeric root powder) having 18% protein, 7.2% fat, 63% carbohydrate, 5% fiber, and 6.8% moisture. AIN-93G+EGCG (replacing 0.05% carbohydrate with 0.05% EGCG) having 18% protein, 7.2% fat, 63% carbohydrate, 5% fiber, and 6.8% moisture. AIN-93G+EGCG+turmeric root powder (replacing 0.05% carbohydrate with 0.05% EGCG and replacing 3% carbohydrate with 3% turmeric root powder) having 18% protein, 7.2% fat, 63% carbohydrate, 5% fiber, and 6.8% moisture. AIN-93G+lycopene (replacing 0.005% carbohydrate with 0.005% lycopene) having 18% protein, 7.2% fat, 63% carbohydrate, 5% fiber, and 6.8% moisture). AIN-93G+fish oil (available from Omega Protein) (replacing 2% carbohydrate with 2% fish oil) having 18% protein, 7.2% fat, 63% carbohydrate, 5% fiber, and 6.8% moisture. AIN-93G+taurine (replacing 0.1% carbohydrate with 0.1% taurine) having 18% protein, 7.2% fat, 63% carbohydrate, 5% fiber, and 6.8% moisture. AIN-93G+maitake mushroom extract (available from Aloha Medicinals Inc.) (replacing 0.0005% carbohydrate with 0.0005% maitake mushroom extract) having 18% protein, 7.2% fat, 63% carbohydrate, 5% fiber, and 6.8% moisture. AIN-93G+walnut meal (Oh! Nuts® available from www.ohnuts.com) (replacing 11.3% carbohydrate with 11.3% walnut) having 21% protein, 8% fat, 57.5% carbohydrate, 5% fiber, and 8.5% moisture. Nutrient blend (NB) composition: 11.3% whole walnut meal, 0.005% maitake mushroom extract, 0.05% EGCG, 3% turmeric root powder, 0.005% lycopene, 0.1% taurine, and 2% fish oil.

The results of the study show that only the “NB” composition reduced cancer occurrence (Table 1), and slowed down cancer growth (Table 2 and 3). Single nutrient supplemented compositions failed to reach similar preventive effects. The data clearly demonstrate that the NB composition provided unexpected cancer prevention effects, which cannot be achieved by single nutrient compositions. Further, the combination of EGCG and “turmeric root powder” also failed to show any cancer prevention effects, which disproves the published cancer treatment effects of EGCG and “Turmeric root powder” as reported in Zhou D H, Wang X, Yang M, Shi X, Huang W, Feng Q. “Combination of low concentration of (−)-epigallocatechin gallate (EGCG) and curcumin strongly suppresses the growth of non-small cell lung cancer in vitro and in vivo through causing cell cycle arrest” Int J Mol Sci. 2013; 14(6):12023-36. The present results are wholly unexpected as the present NB blend utilized EGCG, fish oil, and maitake mushroom extract which individually increased tumor sizes vs the control diet (see Table 2). The present NB composition delivered a strong cancer treatment in animals and can be used for prevention or treatment for animals that are high risk of cancer as well as in animals having completed cancer treatments.
